I am not a huge fan of wrestlers dropping a weight class. A severe cut for 90% of elite guys eventually proves counter productive and we have oodles of examples where going up delivers a better benefit.
That said the two Mirasolas present opportunities and challenges.
My own thinking is Conner while improving, (so too is Barr) I don't see that gap with Josh closing.
I think it was generally accepted two years ago that Conner was a better wrestler than Cole, yet Cole took that as an opportunity to move up and target the roster gap at heavy. Short of Ross or another elite portal-in, Cole is our heavy for a few years.
So what happens with Conner? He could go up and I think in time likely displace his brother at heavy, or could he go down to 184?
In concept he is thick enough physically at 197 to do it, but that's a big 13 lbs, and word has it that he walks around closer to 210 or more. I think this results in too big of a cut to be a top 4 guy with sufficient gas tank to take on Henkle let alone the rest of that 184 field, but that's just me.
In short I don't have a great answer for Conner despite him being the more talented brother.
A bit of a both good and bad problem to have. Both brothers love the program but there is no substitute for competition. If in time Conner decides to portal will Cole follow as a package deal? I am sure Cael is all over every possible scenario, and we know he is still courting Ross, strongly. Hmmm
